Search for double beta decay (beta(+)beta(+), beta(+)/EC EC/EC) of Cd-106 was performed at the Modane underground laboratory (4800 m w.e.) using a spectrometer TGV-2 with 32 HPGe detectors. New limits on the half-lives of 0vEC/EC resonant decay - T-1/2 >= 1.6 x 10(20) y, and on 2vEC/EC decay of Cd-106 - T-1/2 >= 4.1 X 10(20) y (at 90% CL) were obtained from preliminary calculations of experimental data accumulated for 12900 h of measurement of similar to 13.6 g of Cd-106 with enrichment of 75%. The limits on 2vEC/EC decay of Cd-106 to the 2(+),512 keV and 0(1)(+),1334 keV excited states of Pd-106 and on 24 beta(+)beta(+) and 2v beta(+)/EC decay of Cd-106 were improved
